Fermentation is an anaerobic process in which
microorganisms like yeast and bacteria break down food components
(e.g. sugars such as glucose) into other products (e.g. organic acids, gases or alcohol). This gives fermented foods their unique and desirable taste, aroma, texture and appearance.
What is prepared by fermentation?
Fermentation usually implies that the action of microorganisms is desired. The science of fermentation is known as zymology or zymurgy. The term fermentation sometimes refers specifically to the
chemical conversion of sugars into ethanol
, producing alcoholic drinks such as wine, beer, and cider.
What are the 3 products of fermentation?

What is fermentation and what can it be used to make?
For example, fermentation is used for preservation in a process that produces
lactic acid
found in such sour foods as pickled cucumbers, kombucha, kimchi, and yogurt, as well as for producing alcoholic beverages such as wine and beer.
Which is an example of a food product that is created through fermentation?

are examples of foods preserved by fermentation. Sauerkraut undergoes 3–5 stages of bacterial conversion in which sugars are converted to organic acids.
What are the benefits of fermentation give examples?
Fermentation is the breakdown of carbs like starch and sugar by bacteria and yeast and an ancient technique of preserving food. Common fermented foods include kimchi, sauerkraut, kefir, tempeh, kombucha, and yogurt. These foods may
reduce heart disease risk and aid digestion, immunity, and weight loss
